"Our study has an important public health message for women, especially at a time when many women seeking infertility care have endometriosis as their primary diagnosis," said Harvey Kliman, M.D., lead author of the study and a research scientist in the Department of Obstetrics and Gynecology at Yale School of Medicine. "Our study suggests that tampon use could be one of the strongest protectors against endometriosis."
The study, published in the June issue of the journal Gynecologic and Obstetrical Investigation, looked at whether sexual behaviors, orgasm, tampon use and douching during menstruation modifies the risk of endometriosis. Some 2,012 members of the Endometriosis Association, as well as their friends who are not affiliated with the organization, completed mailed surveys.
Although douching during menstruation did not appear to lessen a womans risk of developing endometriosis, Kliman said sexual activity, orgasm and tampon use seemed to play a role in lessening the risk of developing the condition.
Among the women with endometriosis, 26.5 percent said they sometimes or often
engaged in sexual activity during menstruation. Among women who are free of the disease, 34.6 percent said they sometimes or of
